Port the benchmark pipeline to GitHub-hosted runners using the open-source Julia actions (julia-actions/setup-julia, julia-actions/cache), replacing the Buildkite pipeline that ran on the private juliaecosystem queue. The matrix (nightly x serial/multithreaded/all plus slow/bigint), the 60-minute timeout, the [skip tests] escape hatch and the results.csv artifact are carried over unchanged.

Note for merging: GitHub Actions appears to be disabled for this repository (no workflows register and the head commit gets zero check runs — only Buildkite responded to the PR). A repo/org admin needs to enable it under Settings → Actions → General before or when this merges, or the new workflow will silently never run. |

Ports the benchmark pipeline to GitHub-hosted runners using the open-source Julia actions (
julia-actions/setup-julia@v2,julia-actions/cache@v2), replacing the Buildkite pipeline that ran on the privatejuliaecosystemqueue.Carried over unchanged from the Buildkite matrix:
[skip tests]commit-message escape hatchresults.csvuploaded as an artifact per matrix entry (namedresults-<version>-<benchmark>-<category>)Additions that come free with GHA:
pull_requesttriggers (Buildkite only ran on push), per-ref concurrency cancellation, and the Julia depot cache between runs.One honest caveat for reviewers: GitHub-hosted runners are shared 4-vCPU VMs, so timing numbers will be noisier than on the Buildkite fleet — this CI is best read as a does-it-run/regression smoke check, with real measurements still done on dedicated hardware.
